9+ 4 (x + 2) - 3x what is the term that best describes 3 in this expression?

For this case we have that by definition, a coefficient is a factor linked to a monomial.

Example:

- : It's the sign

5: It is the coefficient

x: It is the variable

3: It is the degree

Then, according to the given expression, we can conclude that the number 3 that accompanies the variable "x" is defined as a coefficient.

Option B

(x, y) -> (x + 1, y + 1), (x, y) -> (y, x)

Step-by-step explanation:

I'll use point B (-3,0) for this problem.

First, the translation rule tells us to add 1 to the x value and add 1 to the y value. Now we have (-2, 1). Next, the rule tells us to flip the x and y coordinates. Now we have (1, -2). This matches to vertex B''(1, -2).
